How to Get a Genetic Code by Chance
February 19, 2004
The Feb. 17 issue of Current Biology1 has a Q&A magazine feature on the genetic code.  After dismissing some myths about it being universal, consisting of only 20 amino acids and obligated to only three codons (there are some minor exceptions to these mostly-true principles: see 04/30/2003), the authors tackle the big question: where did […]

Early Man Studies: Start Over
February 19, 2004
Anthropologist Leslea J. Hlusko (U. of Illinois) had some stern advice for her paleoanthropologist colleagues in PNAS1 recently.  Noting that “Competing interpretations of human origins and evolution have recently proliferated despite the accelerated pace of fossil discovery,” she thinks an approach is needed that integrates genetics and development with the search for bones.  She takes […]

Respect the Conch Shell
February 19, 2004
Engineers and materials scientists seem to never run out of examples in nature that should fill us with awe.  In the Feb. 19 issue of Nature,1 Rosamund Daw brings our attention to the construction ability of the conch shell: Giant conches are seldom treated with the respect they deserve.  Their impressive shells are prized as […]

Irreducible Complexity: Can It Be Explained Away?
February 18, 2004
When Sharon Begley, writing in the Wall Street Journal Feb. 13, criticized the intelligent design movement (see reprint on Access Research Network), Michael Behe answered with a pointed reply five days later.  Begley particularly singled out the concept of “irreducible complexity.”  Behe’s reply, defending the validity of irreducible complexity (a term he coined in his […]

Birds Are Memory Champs
February 17, 2004
We humans lose our keys and often can’t remember the location of half a dozen identical items.  “Maybe it takes a bird brain to find the car keys,” teases Susan Milius in the cover story of the Feb. 14 issue of Science News.1  Ornithologists have been intrigued with how birds remember where they stash their […]

DNA Is a Code Operated by Another Code
February 17, 2004
The discovery in the 1950s that DNA stored a coded language was amazing, but recently a new level of complexity has come to the awareness of biochemists.  Apparently, another code determines which DNA genes will be opened for expression and which should be suppressed.     The Feb. 14 issue of Science News1 describes the […]

Scientists Probe Differences Between Living and Nonliving Chemicals
February 15, 2004
“All life forms are composed of molecules that are not themselves alive.  But in what ways do living and nonliving matter differ?  How could a primitive life form arise from a collection of nonliving molecules?”  Any article beginning with questions like that is bound to be interesting.  That’s how Rasmussen et al. tantalized readers of […]

Happy Darwin Day?
February 13, 2004
Humanists hope to have a new international holiday by 2009: Darwin Day.  (Feb. 12 was Darwin’s birthday as well as Abe Lincoln’s, so it’s already set aside as a holiday in America, but promoters want this to be an international event.)  According to Robert Evans’ story in Reuters, the British Humanist Association believes such a […]

New Website Aids Slow Process of Dethroning Darwin
February 13, 2004
A new website, Darwin and Design.com, based on the book co-authored by Stephen Meyer and John Angus Campbell, has been announced by Discovery Institute.  Meanwhile, Ohio anticreationists are trying to caricature a proposed lesson plan on critical analysis of evolution by identifying it with intelligent design theory.  �Intelligent design isn�t even covered in this lesson,� […]

Your Internal Motors Can Run Nanotech
February 13, 2004
In each cell in your body, and in that of every living thing, there exists a tiny motor named ATP synthase that Science News1 calls “the ultimate molecular machine.”  It converts electrical to chemical energy, writes Alexandra Goho, “with amazing efficiency.”  Now, Japanese have harnessed some of these motors (only 12 millionths of a millimeter […]

“Utmost Precision” Found in DNA Repair Enzyme
February 13, 2004
The cell has many helper enzymes that can repair DNA damage.  One such enzyme, named MutY, has been described in the Feb. 12 issue of Nature.1  Reviewer Tomas Lindahl sets the stage: “Damaged DNA must be removed with the utmost precision, as mistakes are costly.  The structure of a repair enzyme bound to its substrate […]

Mercury’s Magnetic Field: Another Attempt to Save Theory from Data
February 13, 2004
Nature Feb. 121 restates a puzzle about Mercury known since the Mariner 10 encounters (1974-5): …why, against expectations, does Mercury have a global magnetic field? The planet’s diminutive size means that it should have cooled quickly after it formed.  Any molten core would have become solid, or almost completely so.  A magnetic-field-generating dynamo in an […]

Oldest Fossil Insect Alleged
February 11, 2004
In a pattern that sounds familiar, an insect fossil has been found that (1) is the oldest ever discovered, and (2) shows that “winged flight may have emerged earlier than previously thought.”  Estimates put this fossil at about 400 million years old, among the first creatures to colonize the land.  Though wing impressions were not […]

Darwinians Excel at Games
February 10, 2004
Martin Nowak (Harvard) sure got good press for his evolutionary game theories last week.  In Nature,1 he retold the glorious story of how he and Karl Sigmund met in an Austrian mountain cottage and applied the “prisoner’s dilemma” game to a new theory for social evolution.  The same week, in Science,2 as part of a […]

Comets as Cosmic Storks
February 10, 2004
Chandra Wickramasinghe and colleagues at Cardiff University have raised the bar on tale-telling ability.  They believe that comets splatting on earth can carry away germs of life that gradually spread farther and farther out, eventually escaping the sun’s pull.  Over time, they might spread life to other worlds.  They estimate that since the origin of […]
